install iodocs on linux

Question

I had this problem initially, so I tried

npm install --force

It seems to work, with only one warning:

npm WARN querystring@0.0.1 package.json: bugs['web'] should probably be bugs['url']

But when I try to run it, it gives me:

[ec2-user@ip-10-136-14-95 iodocs]$ node ./app.js
The "sys" module is now called "util". It should have a similar interface.

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
Error: Cannot find module 'hashlib'

    at Module.load (module.js:348:31)
    at Function._load (module.js:308:12)
    at Array.0 (module.js:479:10)

I have no idea what to do with it, please shed some light on me.

BTW, I'm trying to install iodocs on a Linux 2.6.35.14-97.44.amzn1.x86_64 EC2 instance.

Answer 1

I came across the same issue exactly.

I think there's a "Pull Request" that might fix this: https://github.com/mashery/iodocs/pull/14

I'm going to implement it and if it works, will report.

EDIT:

I was able to get farther. Here are some things you need to do:

1. implement the pull request linked above
2. in package.json, update your "express": "2.5.8" (the version they have 2.4.8. isn't compatible with node.js v1.0.0
3. remove the "hashlib" directory from "iosdocs/node_modules"

npm install should now work.

However, if you run node ./app.js, I'm getting this error:

The "sys" module is now called "util". It should have a similar interface. Express server listening on port 3000

node.js:201 throw e; // process.nextTick error, or 'error' event on first tick

EDIT #2:

Figured it out! You have to actually run redis-server (DUH).

So I did the following:

1. Download redis 2.4.8 from their site
2. Follow their instructions in unzipping, building
3. run the server with src/redis-server

Bam, NOW run node ./app.js and it works!

Answer 2

I came across the same module error for hashlib. After troubleshooting it, I wiped the iodocs folder and used jsonmccreary's fork of iodocs instead.

After cloning the repo, here's what I did:

1. npm install
2. installed redis-server sudo apt-get install redis-server
3. started running the redis-server 'redis-server'

Now, running node ./app.js works!

EDIT:

Jason talks about some issues configuring heroku for iodocs on his blog which is where I found his fork from.
